hosts_allow - decide if a host is allowed to connect
= [[#___top|DESCRIPTION]] =
The '''hosts_allow''' module decides before the SMTP-Greeting if a host is allowed to connect. It checks for too many (running) connections from one host (see -m/--max-from-ip options in qpsmtpd-forkserver) and the config file ''hosts_allow''.
The plugin takes no config/plugin arguments.
This plugin only works with the forkserver and prefork deployment models. It does not work with the tcpserver deployment model. See SEE ALSO below.
= [[#___top|CONFIG]] =
The ''hosts_allow'' config file contains lines with two or three items. The first is an IP address or a network/mask pair. The second is a (valid) return code from Qpsmtpd::Constants. The last is a comment which will be returned to the connecting client if the return code is DENY or DENYSOFT (and of course DENY_DISCONNECT and DENYSOFT_DISCONNECT).
Example:
<pre> 192.168.3.4 DECLINED
192.168.3.0/24 DENY Sorry, known spam only source</pre>
This would exclude 192.168.3.4 from the DENY of 192.168.3.0/24.
= [[#___top|SEE ALSO]] =
To get similar functionality for the tcpserver deployment model, use tcpserver's -x feature. Create a tcp.smtp file with entries like this:
<pre> 70.65.227.235:deny
183.7.90.207:deny
:allow</pre>
compile the tcp.smtp file like this:
<pre> /usr/local/bin/tcprules tcp.smtp.cdb tcp.smtp.tmp < tcp.smtp</pre>
and add the file to the chain of arguments to tcpserver in your run file.
